Description:
The Create Line Description (Ethernet) (CRTLINETH) command creates a line description for an Ethernet line.
Common Errors for CRTLINETH
In order to avoid common configuration errors, determine the port configuration of your switch or hub prior to configuring your line description. The line description parameters and the port configuration must match in order for operating system to communicate properly with the network.
Use the following guidelines when configuring your line description:
. If the switch or hub auto-negotiates either the line speed or duplex, specify *AUTO for both the LINESPEED and DUPLEX parameters. Do not specify LINESPEED(100M) or LINESPEED(10M) and DUPLEX(*FULL).
. If the switch or hub does not auto-negotiate either the line speed or duplex, specify the corresponding values on the system. For example, if the switch specifies a line speed of 100M and full duplex, specify LINESPEED(100M) and DUPLEX(*FULL) on the command.
One frequent cause of problems is a mismatch between the duplex setting of an auto-negotiation capable adapter like the 2838 and the switch or hub. In the case of auto-negotiation, duplex is not detectable by either the switch, hub, or the auto-negotiation capable adapter. So, there is no way to notify the user of a mismatch. Symptoms of a duplex mismatch include:
. A6E3, A6F4 reference codes
. Poor performance
. Large numbers of TCP/IP retransmits
Examples:
Example 1: Creating an Ethernet Line Description
CRTLINETH LIND(BOSTON) RSRCNAME(LIN041)
This command creates an Ethernet line description named BOSTON with a resource name of LIN041.
Example 2: Creating an Ethernet Line Description Attached to a Network Server
CRTLINETH LIND(ETHLIN) RSRCNAME(*NWSD) NWS(REMODEL 1)
This command creates an Ethernet line description named ETHLIN that is attached to port 1 of the network server REMODEL.
Example 3: Creating a Gigabit Ethernet Line Description
CRTLINETH LIND(GIGETH) RSRCNAME(LIN041) LINESPEED(1G)
DUPLEX(*FULL) MAXFRAME(8996)
This command creates an Ethernet line description using the maximum gigabit ethernet connectivity configuration.
